Example Question #162 : Cellular Division
What is the difference between anaphase I and anaphase II?
During anaphase I, the sister chromatids separate from each other and in anaphase II the pair of homologous chromosomes separate from each other.
During anaphase I, the chromosomes line up along the metaphase plate and in anaphase II, the chromosomes separate from each other.
During anaphase I, the pair of homologous chromosomes separate from each other and then in anaphase II the sister chromatids separate from each other.
There are no differences between the two.
During anaphase I, the pair of homologous chromosomes separate from each other and then in anaphase II a different pair of homologous chromosomes separate from each other.
During anaphase I, the pair of homologous chromosomes separate from each other and then in anaphase II the sister chromatids separate from each other.
During anaphase I, it is just like mitosis. There is a pair of homologous chromosomes (two X's) and they separate into two daughter cells. Anaphase II is a continuation of cellular division so instead of separating a pair of homologous chromosomes it separates sister chromatids of one chromosome (one X) into two daughter cells.
Example Question #165 : Cellular Division
What is the correct order of meiosis?
1. Prophase I, prophase II, metaphase I, metaphase II.
2. Anaphase I, anaphase II, telophase I, telophase II.
1. Prophase I, metaphase I, anaphase I, telophase I.
2. Prophase II, metaphase II, anaphase II, telophase II.
1. Prophase II, metaphase II, anaphase II, telophase II.
2. Prophase I, metaphase I, anaphase I, telophase I.
1. Prophase I, metaphase I, telophase I, anaphase I.
2. Prophase II, metaphase II, telophase II, anaphase II.
1. Prophase , metaphase, anaphase, telophase.
2. Prophase, metaphase, anaphase, telophase.
1. Prophase I, metaphase I, anaphase I, telophase I.
2. Prophase II, metaphase II, anaphase II, telophase II.
The stages of meiosis are just like mitosis except that the division is done twice for every cell and that there are roman numerals for each division (I = 2n to 2n, II = 2n to n).
Overall, there will be four daughter cells for each parent cell in meiosis. For mitosis there are only two daughter cells for each parent cell.
